New applications of photoelectron spectroscopy have been found in the elucidation of the course of gas phase reactions and the optimization of such reactions. For example, a PES analytical technique has been developed for acetonitrile (1) , cyanogen (2) , malononitrile, and hydrogen cyanide; the reaction of (1) with (2) was subsequently monitored by PE spectroscopy. The copper‐catalyzed formation of benzonitrile (3) in the gas phase could be optimized: about 40 wt% of (3) were formed in a single passage over Cu/AI 2 O 3 at 850 K/10 torr.
